Betelgeuse has entered an uncommon period of brightening again, this time rising in brightness by around 50 percent. Is the star about to go supernova?
This is what Betelgeuse may have looked like up until about 1 million years ago, when it was a main-sequence star. The surface of Betelgeuse shows enhancement of nitrogen, relatively low levels of carbon, and a high proportion of 13 C relative to 12 C , all indicative of a star that has experienced the first dredge-up .
Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star suggest it is both smaller — and closer — than astronomers ...
Betelgeuse; Epsilon Pegasi; Zeta Cephei; Lambda Velorum; Eta Persei; 31 and 32 Cygni; Psi 1 Aurigae; 119 Tauri; Mira was historically thought to be a red supergiant star, but is now widely accepted to be an asymptotic giant branch star. [32] Some red supergiants are larger and more luminous, with radii exceeding over a thousand times that of ...

We're miles deep into Camp Pendleton, connected to ViaSat's SurfBeam 2 Pro Portable mobile satellite transceiver and sending data to and from ViaSat-1 located more than 20,000 miles above our heads.
The facility was laid out in 1911, with construction beginning in 1912, [6] as the State Rifle Range for the use of the state militia. Between 1922 and 1942, it was named after the then serving Governor of Virginia, being firstly named Camp Trinkle (1922–1926), then Camp Byrd (1926–1930), Camp Pollard (1930–1934), Camp Peery (1934–1938), and Camp Price (1938–1942).

Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, [61] probably in 1.0 to 1.4 million years. [10] For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime. [53]
